I can see people putting Adam and Jason ahead of Vincent as of right now. The USFS put a less rough than Vincent Nathan Chen in third at 2016 Nationals despite having all of those quads. Adam was not able to compete at 2017 Nationals due to injury but was coming off of what was his most successful GP season and Jason was coming back from injury and skated in less-than-optimal health at Nationals. Jason has shown he is a competitor and could be counted on for a respectable to amazing performance and a respectable result. Adam is a question mark coming into this season, but if he has a quad and the judges continue to give him great GOE and PCS, then he could be a threat to Vincent. It will be in Vincent's best interest to make sure he upgrades his quads AND fully rotates them all of the time and to clean up his skating if he wants to be more of a sure thing to make the team. The types of scores Jason and Adam get internationally even without consistent quads is rare, but they get them and it makes them competitive. Now, once Vincent starts doing Nathan-like variety of quads, the situation changes. Cleaning up his skating will improve his PCS to make him more competitive with Adam and Jason there (even if there is still a huge gap).
